End-to-End QA Services for IoT Climate Control Platforms

The Story

The client expanded its IoT-driven climate control platform with multiple applications for consumers and service partners. As the product scaled across European markets, they required a structured QA partner to stabilize subscription workflows, streamline global payments, and automate repetitive test cycles. FiftyFive Technologies was engaged as the dedicated QA and engineering partner to implement automated testing, validate subscription logic, and ensure reliable transactions across regions. The focus was to strengthen platform performance without altering existing architecture.

The client is a Sweden-based IoT energy technology company delivering smart climate control systems across Europe, supporting residential users, technicians, and administrators through a multi-region digital ecosystem.

Challenges

• > Complex multi-tier subscription logic requiring validation across consumer and professional interfaces.

• > Google API–based address validation errors impacting user onboarding and requiring removal post-release.

• > Migration from Nets to Stripe for secure global payment processing.

• > Recurring payment failures in Norway and Germany requiring root-cause analysis and resolution.

The Solution

• > Implemented automated API and UI testing utilizing Cypress and Postman for recurring validation.

• > Conducted end-to-end subscription and e-commerce testing including trials, renewals, VAT rules, and regional pricing flows.

• > Automated Service Partner workflows to reduce manual regression cycles and accelerate release readiness.

• > Established continuous QA processes with structured smoke, regression, and sanity testing for each deployment.

The Outcome

FiftyFive’s QA framework stabilized subscription operations, reducing support tickets by improving accuracy of billing and renewals. Payment reliability increased after Stripe migration, lowering regional failures and improving successful transactions across Europe. Automated Service Partner workflows cut manual testing effort by over 40%, resulting in faster release cycles and reduced operational overhead. Earlier issue detection improved deployment quality, strengthening user trust and supporting scalable growth of the client’s IoT climate control platform.
